Aaron Roodman is a Professor of Particle Physics & Astrophysics at the SLAC National Accelerator Laboratory at Stanford, specializing in observational cosmology. He received his undergraduate degree in physics at the California Institute of Technology and a Ph.D. at the University of Chicago. Trained in experimental particle physics, he spent two decades studying differences between matter and antimatter at both Fermilab and SLAC with the BaBar experiment, before turning his research to astrophysics and cosmology, initially with the Dark Energy Survey.
He played a major role in the construction of the LSST Camera, the world's largest digital camera, and was the leader of the LSST Camera program and Deputy Director of the Rubin Observatory during its commissioning phase. Currently he is the Deputy Head of the Legacy Survey of Space and Time as part of Rubin Observatory operations, and his current research focuses on the study of Dark Energy via gravitational lensing.
